Trying to Bake Texture, but it's saying that it's a uninitialized image?
Create a new blank image with transparency (choose your size, maybe 2K resolution). In the current shader tree, include a texture image connected to a diffuse shader.

Your procedural shader network should be mixed with the image node->Diffuse with a Mix shader node. Lastly that node should connect to material output.

Your viewport should still be showing your procedural shader only.
Now go to the render properties, scroll down to bake, and choose (diffuse). Press bake.

If you make a screen capture, of your setup that would help as well.
